Tablet talks to keyboard by Bluetooth, as so many other iPad keyboard attachments do, but a pricier version of the product has stereo speakers on board to relay the iPad's output. The keyboard has its own battery, charged over a micro USB link.

The team is taking advance orders now by way of Kickstarter pledges that price the basic model at $150 (£93) - or $180 (£111) for the model with speakers. Brydge will ship internationally. ®
